Heddle

Abstract

In a heddle ( 6 ), the slender heddle shank ( 21 ) has been lengthened, at the cost of the end eyelets ( 7, 8 ) and the yarn eyelet region ( 29 ). This is accomplished on the one hand by shortening the end eyelet regions ( 7, 8 ) to their absolute minimum length and on the other by placing the auxiliary openings ( 38 ), which serve to transport the heddles, closer to the end eyelets ( 7, 8 ). The radii R in the region of the end eyelets ( 7, 8 ) are reduced. Instead of the usual 2 mm width, the heddle shank ( 21 ) still has a maximum width of 1.6 mm. The regions ( 14, 13 ) of the heddle ( 6 ) that protrude past the end openings still have, instead of the usual length of 4 mm, a length of 2.5 mm to 3 mm. Directly around the yarn eyelet ( 33 ), the heddle has a width which, as before, is equivalent to twice the width of the yarn eyelet ( 33 ). However, the length of this region is shortened to a maximum of twice to three times the yarn eyelet width. The transition from the narrowest zone ( 27, 28 ) of the heddle shank ( 21 ) to the comparatively wide zone ( 29 ) around the yarn eyelet ( 33 ) is characterized by an elongated transition region ( 34 ), which has a maximum width of 1.8 mm and serves to reinforce this region against mechanical stresses.

 the yarn eyelet region has a length which is at most five times as great as the width of the yarn eyelet. 
 
   
   
     7. The heddle of  claim 6 , wherein the length of the yarn eyelet region is at most three times as great as the width of the yarn eyelet. 
   
   
     8. The heddle of  claim 6 , wherein the yarn eyelet region, with at least one curved edge (radius R 1 ), merges with the rest of the heddle shank. 
   
   
     9. The heddle of  claim 8 , wherein the radius (R 1 ) of the curved edge is at most 60 mm. 
   
   
     10. A heddle, having
 a heddle shank, and 
 a yarn eyelet region which has at least one yarn eyelet, and wherein 
 adjoining the yarn eyelet region, a transition region is embodied which is defined at least in a portions by edges parallel to one another, and whose width is greater than the least width of the heddle shank and is less than that of the yarn eyelet region. 
 
   
   
     11. The heddle of  claim 10 , wherein the length of the transition region is at most as great as 1.5 times the length of the yarn eyelet region. 
   
   
     12. The heddle of  claim 10 , wherein the heddle shank has an uneven side face. 
   
   
     13. The heddle of  claim 12 , wherein the side face has face regions which form an obtuse angle with one another. 
   
   
     14. The heddle of  claim 12 , wherein the side face is curved. 
   
   
     15. The heddle of  claim 10 , wherein characterized in that the heddle shank has an uneven side face. 
   
   
     16. The heddle of  claim 15 , wherein the side face has face regions which form an obtuse angle with one another.
